Cold sores refer to small painful blisters around the lips, nose, or mouth and are caused by the herpes simplex virus.
They are contagious and may spread through kissing and sharing the same utensils, such as spoons, forks, or towels.
In most cases, cold sores go away on their own within one to two weeks.
Unfortunately, a poor immune system, cold illness, cold wind, or hot sun can increase the risk of cold sores.
Prescribed creams or antiviral medicine can help in healing the sores.
Cold sores can occur at any stage of life and can recur three to four times per year.
Sometimes, the virus may stay in the body inactive and only gets active due to some triggers.

What is a cold sore?
A cold sore is a tiny throbbing blister that usually appears around the nose, lips, face, chin, or on the skin around the mouth.
The blisters are fluid-filled and grouped in patches. The break of a blister forms a scab that remains for many days.
Cold sores on the lips usually affect only one side of the mouth, and within 2-3 days, the blister seeps out and makes a crust—the area where the sores form gets red and swells.
The sensation of tingling, burning, and itching starts when the sores will form, and this happens 12-24 hours before the sores develop.

What causes a cold sore?
A virus known as herpes simplex virus type-1 is the primary cause of cold sores. According to the World Health Organization (WHO), about 3.7 billion people under the age of 50 globally have herpes simplex type-1 infection.

When the sores get cleared, the virus may move toward nerves and stays there as long as it gets reawakened. The virus can also spread to the eyes or genitals.
Some risk factors, such as the following, can increase the risk of cold sores and their recurrence:
- Physical or emotional stress
- Laser treatment
- Cold, flu, or fever Illness
- Very hot or cold temperature
- Too much sunlight exposure
- Hormonal variations like periods or pregnancy
- Cosmetic surgery
- Cracked or dry lips

In most cases, cold sores usually get cleared within 7-10 days without treatment. However, if topical or oral medications are used, the sores may start crusting and resolving within 24-48 hours.

- Avoid the touch: Do not touch your sores; keep your hand away from them. If you touch it accidentally, wash your hands and do not touch the other person without washing.
